Causes of Scalp Fungal Infections
Scalp fungal infections are primarily caused by dermatophytes, a type of mold-like fungus that thrives in warm and humid environments. Certain factors can increase the risk of developing these infections, including:
- Minor injuries to the scalp or skin.
- Poor hygiene practices, such as infrequent washing of hair and scalp.
- Prolonged moisture on the skin, often due to excessive sweating.
- Direct contact with infected areas on another person’s body or the use of contaminated items, such as hairbrushes, hats, or clothing.
- Interaction with infected pets.
Symptoms of Scalp Fungal Infections
Individuals suffering from scalp fungal infections may experience a variety of signs and symptoms, which can include:
- Itchy patches on the scalp, which is among the most common symptoms.
- Scaly or red areas on the scalp, as well as bald spots resulting from hair loss, where black dots may be visible in place of lost hairs.
- Brittle hair.
- Pain or tenderness in the scalp.
- Swollen lymph nodes.
- Low-grade fever.
- Kerion, a severe condition characterized by crusty swellings that may be filled with pus; it can lead to permanent bald patches and scarring in advanced cases of scalp fungal infections.
When to Consult a Physician
It is essential for individuals experiencing any symptoms indicative of a scalp fungal infection to seek medical attention promptly. Accurate diagnosis and appropriate treatment are crucial since the symptoms can resemble those of other conditions such as psoriasis or dandruff. Each condition has distinct treatment protocols. It is important to note that the treatment for fungal infections is not immediate; recovery may take several weeks to months.
